Write a method so that the main() code below can be replaced by the simpler code that calls method mphAndMinutesToMiles(). Origi
defon

ANSWER

The JAVA program after simplification is as below.

import java.util.Scanner;

public class CalcMiles {

   

   // variables declaration

   static double milesPerHour;

   static double minutesTraveled;      

   static double hoursTraveled;

   static double milesTraveled;

   

   // method declared static

   public static void mphAndMinutesToMiles(double speed, double mins)

   {

       // computations to calculate distance travelled

       hoursTraveled = mins / 60.0;

       milesTraveled = hoursTraveled * speed;

       

       // result displayed on the screen  

     System.out.println("Miles: " + milesTraveled);

   }

   

   // Scanner object created inside main()

   // user input taken inside main()

   public static void main(String [] args)

   {

       Scanner scnr = new Scanner(System.in);

       System.out.println("Enter miles travelled per hour ");

       milesPerHour = scnr.nextDouble();

       System.out.println("Enter minutes required to travel ");

       minutesTraveled = scnr.nextDouble();

       

       mphAndMinutesToMiles(milesPerHour, minutesTraveled);

       

   }

}

OUTPUT

Enter miles travelled per hour  

2.3

Enter minutes required to travel  

1234

Miles: 47.30333333333333

EXPLANATION

The program is simplified as explained below.

1. User input is taken using the object of Scanner class.

2. This object of Scanner class can only be created inside main() method hence, user input can only be taken inside main().

3. The code to calculate the result is separated in another method, mphAndMinutesToMiles(). This method is declared with return type void since no value is returned.

4. After user input is taken in main() for miles travelled per hour and minutes required to travel, these values are passed as parameters to the mphAndMinutesToMiles() method.

5. These parameters are used in calculation part. The total miles travelled in total hours (obtained from minutes), is calculated. The code to display the result is added to this method.

6. Inside the main method, only the code to create Scanner object, code to take user input for two variables and code to call the mphAndMinutesToMiles() is included.

7. The variables are declared as static and declared at class level.

8. No variable is declared inside any of the two methods.

Design a program for the Hollywood Movie Rating Guide, which can be installed in a kiosk in theaters. Each theater patron enters
ehidna [41]

Answer:

The program in cpp is given below.

#include <iostream>

using namespace std;

int main()

{

   //variables declared to hold sum, count and average of movie ratings

   int sum=0;

   int count=0;

   int rating;

   double avg;

   //audience is prompted to enter ratings

   do{

       std::cout << "Enter the rating (0 to 4): ";

       cin>>rating;

       if(rating>4)

           std::cout << "Invalid rating. Please enter correct rating again." << std::endl;

       if(rating>=0 && rating<=4)

       {

           sum=sum+rating;

           count++;

       }

       if(rating<0)

           break;

   }while(rating>=0);

   //average rating is computed

   avg=sum/count;

   std::cout << "The average rating for the movie is " << avg << std::endl;  

   return 0;

}

OUTPUT

Enter the rating (0 to 4): 1

Enter the rating (0 to 4): 2

Enter the rating (0 to 4): 0

Enter the rating (0 to 4): 5

Invalid rating. Please enter correct rating again.

Enter the rating (0 to 4): 1

Enter the rating (0 to 4): -1

The average rating for the movie is 1

Explanation:

1. Variables are declared to hold the rating, count of rating, sum of all ratings and average of all the user entered ratings.

2. The variables for sum and count are initialized to 0.

3. Inside do-while loop, user is prompted to enter the rating for the movie.

4. In case the user enters a rating which is out of range, the user is prompted again to enter a rating anywhere from 0 to 4.

5. The loop executes until a negative number is entered.

6. Inside the loop, the running total sum of all the valid ratings is computed and the count variable is incremented by 1 for each valid rating.

7. Outside the loop, the average is computed by dividing the total rating by count of ratings.

8. The average rating is then displayed to the console.

9. The program is written in cpp due to simplicity since all the code is written inside main().
